Krypton Virus – Details

Krypton is a virus that encrypts your files and extorts you to pay a ransom to get them decrypted. Malware researchers have discovered that it is a variant of the HiddenTear open-source project. The ransom payment is demanded in BitCoin.

Krypton ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

That ransom message appears inside a file called “KRYPTON_RANSOMWARE.txt” which can be seen in the form of a picture background as seen in the screenshot here:

It reads the following:

All your files have been encrypted by Krypton Ransomware Please pay 158$ USD in Bitcoin to us and we will decrypt your files. Not paying after 1 week (168 hours) will result in a loss of all your files.

The following window screen with ransom instructions will also show up:

Those instructions state the following:

The note of the Krypton ransomware states that your files are encrypted. The ransom payment for potentially unlocking your files is not stated. However, even if it was, you should NOT under any circumstances pay any ransom. Your files may not get restored, and nobody could guarantee that. Moreover, giving money to cybercriminals will likely motivate them to create more ransomware viruses or commit other crimes.

Krypton Virus – Encryption Process

As Krypton ransomware is a HiddenTear variant it could seek to encrypt files with these extensions:

Every single file that gets encrypted will receive the same extension appended to it, which is .kryptonite. The encryption algorithm which is implemented is undoubtedly AES since it is a variant of the HiddenTear open-source ransomware project.

The Krypton cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

If the command stated above is executed that would make the encryption process even more efficient as it will eliminate one of the possible ways for restoring your data. If your computer machine was infected with this ransomware and your files are locked, read on through to find out how you could potentially recover your data.
